heat_transfer_coefficient_simple {TrenchR}

Estimate the Heat Transfer Coefficient using Simple Relationships

Description

The function estimates the heat transfer coefficient (Mitchell 1976) using either the relationship in Spotila et al. (1992) or that in Gates (1980).

Usage

heat_transfer_coefficient_simple(u, D, type)

Arguments

u

numeric air velocity (m s^-1).

D

numeric characteristic dimension (e.g., diameter or snout-vent length) (m).

type

character choice between "Spotila" and "Gates" for equation to use.

Value

numeric heat transfer coefficient, H_L (W m^-2 K^-1).
